Study of the montmorillonite clay reinforced plasticized starch (PS) nanocomposites is carried out. Both, native (V) and organically modified (D72) nanoclays are used as nanofillers. The nanoclay content is varied from 1 to 6 wt. %. Structures as well as tensile and sorptive properties of the PS/V and PS/D72 nanocomposites are investigated. Results of the tensile investigations show that due to the intercalated structure tensile strength and Young‘s modulus of the investigated nanocomposites are substantially increased with addition of minor amounts of the clay nanofiller. Moisture sorption/desorption rates in the investigated nanocomposites at the same time are effectively reduced.
